Amazing Penthouse with own elevator and two terrace in Köln

Living directly in the green (Rochuspark) and yet central. In a well-kept, modern 12 party house with 3 floors and elevator. The complex was completed in 2020. The property has an energy consumption index of 23,1 kWh/(m2*a). Due to a central softening plant the water is pleasantly "soft" and lime residues are reduced.
The object was built and equipped according to the latest energy saving measures.
The object was built in ecological construction with monolithic insulating bricks and the roof was insulated with recycled paper.
No fossil fuels are used. The central underfloor heating is supplied by an air-heat exchanger. Hot water is provided by green electricity. The building is efficiently insulated and the wooden windows are triple glazed. Thus, the property hardly heats up even in summer.
